The controller working the ROBER sector in the JFK area of N90 (NY TRACON; more generally NY Approach) pointed out a "violating aircraft" to JBU1005 who's mode C reported 2400 feet today around 1434z. The JetBlue pilot reported the traffic at 2500 on TCAS, but due to some haze, they didn't make contact with the a/c and therefore couldn't see the N-number.

The JetBlue pilot made a remark that went something like this: "..and a very happy fathers day to our violator"...the controller responded: "Yea, I'm sure he's not going to like the phone call hes going to get"
